I don't understand why people expect Apple to release a market-shaking new product every year and are actively disappointed and say things like 'Apple are done innovating' when it doesn't happen. This is not how it works. Firstly, products that go to new places take a long time to get right. Apple worked on the iPhone and iPad for years before they were released. In fact Apple started on the iPad before the iPhone. Secondly, if there's too many changes too quickly any impact each may have is lessened. If in 2007 after releasing the iPhone Apple's management said 'Right, we've done this touch screen stuff. Let's come up with a different interface method', the iPhone (and touchscreen computing in general) would not be the force it is today. Implications of each change need time to sink in and be explored properly. Thirdly, it's not how Apple works. They come up with a new product category once or twice a decade and iterate on it annually year until it becomes mature. Fourthly, who knows what else Apple's been working on over the last few years? The attitude assumes that there's nothing more going on, that some of the world's brightest people with practically unlimited resources are just watching cat videos all day. Now Apple may well be done innovating, but for the author to say that without any actual knowledge seems hasty, and more like he's disappointed he didn't get a pony.
